SYSTEM FOR SIMULTANEOUS PRODUCTION AND MAINTENANCE WITH MECHANICAL PUMPING WITH FLEXIBLE PIPE FOR FLUID EXTRACTION

摘要

A system for production of fluids from a well, including the simultaneous extraction of fluids and mechanical pumping of fluids with flexible tubing for maintenance of the well, comprising a surface assembly that includes a sub-base, a hydraulic traction head, a stuffing box system, an annular seal blowout preventer, a slip blowout preventer and means for connecting and coupling; a production string system extending vertically down into a well from the surface assembly; a well casing system; a flexible pipe system located inside the production string system, extending the entire length thereof, the well casing, the production string and the flexible pipe systems remaining one inside the other concentrically; and a pumping assembly that includes a connector, a check valve, a cleaning tool and a stationary pump. The system enables production with mechanical pumping for the extraction of fluids, and maintenance by the simultaneous pumping of chemical products to the well to modify the physical properties of the fluid to be extracted and to clean the deposit of organic and inorganic material in the well.
